I have ECS4300H-H3 (CM4300H + 2*CS4300H)
Is it ok to add 2*Q5000-S in the same stack?
If possible, is there anything special to consider, a short instruction would be good.
No you can only install additional CS4300H in the same stack.
When adding new slaves, add them between the CM4300 and the next battery in the stack, make sure the existing stack is approx 50% SoC (+/- 3%) when fitting the new battery and once added make sure the firmware is the same across all slaves - your installer or Fox can arrange the firmware to be updated remotely.

You're unlike to still find CS4300 but you can use EQ4300 compatible. You just can't go bigger or small models as per Dave.
